A mother and her son were flying Southwest Airlines from Kansas City to Chicago. The son (who had been looking out the window) turned to his mother and asked, "If big dogs have baby dogs and big cats have baby cats, why don't big planes have baby planes?"

The mother (who couldn't think of an answer) told her son to ask the stewardess. So the boy asked the stewardess, "If big dogs have baby dogs and big cats have baby cats, why don't big planes have baby planes?"

The stewardess responded, "Did your mother tell you to ask me?" The boy admitted that this was the case. "Well, then, tell your mother that there are no baby planes because Southwest always pulls out on time. Your mother can explain that to you."

A young married couple has difficulties conceiving a baby, so after a while the wife consults her doctor, who recommends the minor of three possible operations.

The operation is performed, but a couple of months later, she's still not pregnant, so she goes to see the doctor again. This time he recommends the medium operation, a somewhat more serious operation, but still not as complicated as the third alternative.

But, there's still no result, and another couple of months later she's back in the doctor's office, and this time she gets the big one. After having recovered in some weeks, the couple resumes normal marital activities, and this time they actually succeed in conceiving a baby.

Filled with joy, the young wife now sees the doctor for the regular examination during pregnancy and says, "We're so happy doctor, we're finally having a baby. But what was this third operation actually all about? The first two weren't that bad, but this last one I think must have been quite a job, I was dizzy for weeks after."

"Well," the doctor replies, "since the first two standard operations failed, we started suspecting your method rather than your ability, so I made a connection from your throat to your uterus."
